Henry V, (August 9 or September 16, 1387 – August 31, 1422), King of England, son of Henry IV of England by Mary de Bohun, was born at Monmouth, Wales, in September 1387. On his father's exile in 1398, Richard II took the boy into his own charge, and treated him kindly. Next year the Lancastrian revolution forced Henry into precocious prominence as heir to the throne.
From October 1400 the administration of Wales was conducted in his name; less than three years later Henry was in actual command of the English forces and fought against Harry Hotspur at Shrewsbury. It was there, in 1403, that the sixteen-year-old prince was almost killed by an arrow which became lodged in his face. An ordinary soldier would have been left to die from such a wound, but Henry had the benefit of the best possible care, and, over a period of several days after the incident, the royal physician crafted a special tool in order to extract the tip of the arrow without doing further damage. The operation was successful, and probably gave the prince permanent scars which would have served as a testimony to his experience in battle.
The Welsh revolt of Owen Glendower absorbed Henry's energies until 1408. Then, as a result of the king's ill-health, he began to take a wider share in politics. From January 1410, helped by his uncles Henry and Thomas Beaufort – legitimised sons of John of Gaunt – he had practical control of the government.
Both in foreign and domestic policy he differed from the king, who in November 1411 discharged the Prince from the council. The quarrel of father and son was political only, though it is probable that the Beauforts had discussed the abdication of Henry IV, and their opponents certainly endeavoured to defame the prince. It may be to that political enmity the tradition of Henry's riotous youth, immortalized by Shakespeare, is partly due. Henry's record of involvement in war and politics, even in his youth, disproves this tradition. The most famous incident, his quarrel with the chief justice, has no contemporary authority and was first related by Sir Thomas Elyot in 1531.
The story of Falstaff originated partly in Henry's early friendship for Sir John Oldcastle. That friendship, and the prince's political opposition to Thomas Arundel, Archbishop of Canterbury, perhaps encouraged Lollard hopes. If so, their disappointment may account for the statements of ecclesiastical writers, like Thomas Walsingham, that Henry on becoming king was changed suddenly into a new man.
Henry succeeded his father on March 20, 1413. With no past to embarrass him, and with no dangerous rivals, his practical experience had full scope. He had to deal with three main problems:
Henry tackled them all together, and gradually built on them a wider policy. From the first he made it clear that he would rule England as the head of a united nation, and that past differences were to be forgotten. The late king Richard II of England was honourably reinterred; the young Mortimer was taken into favour; the heirs of those who had suffered in the last reign were restored gradually to their titles and estates. With Oldcastle Henry used his personal influence in vain, and the gravest domestic danger was Lollard discontent. But the king's firmness nipped the movement in the bud (January 1414), and made his own position as ruler secure. Save for the abortive plot in favour of Mortimer, involving Henry Scrope and Richard, Earl of Cambridge (grandfather of King Edward IV of England) in July 1415, the rest of his reign was free from serious trouble at home.
Henry could now turn his attention to foreign affairs. A writer of the next generation was the first to allege that Henry was encouraged by ecclesiastical statesmen to enter into the French war as a means of diverting attention from home troubles. For this story there is no foundation. The restoration of domestic peace was the king's first concern, and until it was assured he could not embark on any wider enterprise abroad. Nor was that enterprise one of idle conquest. Old commercial disputes and the support which the French had lent to Glendower was used as an excuse for war, whilst the disordered state of France afforded no security for peace. Henry may have regarded the assertion of his own claims as part of his kingly duty, but in any case a permanent settlement of the national quarrel was essential to the success of his world policy. The campaign of 1415, with its brilliant conclusion at Agincourt (October 25), was only the first step. Two years of patient preparation followed.
The headship of Christendom was in his grasp, and schemes for a new Crusade began to take shape. He actually sent an envoy to collect information in the East; but his plans were cut short by death. A visit to England in 1421 was interrupted by the defeat of Clarence at Baugé. The hardships of the longer winter siege of Meaux broke down his health, and he died of dysentery at Bois de Vincennes on August 31, 1422. Had he lived another two months, he would have been crowned King of France.
